Hi @erania-pinnera,
Thanks for your reply!
Could you please explain more in detail.
here is an example – from the quote section https://prnt.sc/132huy7
I want to display the value in the invoice letter template (https://prnt.sc/132hx55) – set using the custom field https://prnt.sc/132hyh6.
How can I register this variable in the invoice letter template (https://prnt.sc/132i00d) so that not ### INV-ORDER-NUMBER ### are displayed, but the specified value in the invoice itself?
Your help is much appreciated.
Thank You
